Classic API Focus (#2)
* focus: migrate to FocusUnit / "focus" token / PLAYER_FOCUS_CHANGED
ClassicAPI now polyfills modern WoW's focus system: FocusUnit / ClearFocus
+ "focus" / "focustarget" unit tokens accepted by every UnitX function +
PLAYER_FOCUS_CHANGED event. Drop pfUI's GUID-juggling pseudo-frame.
- env/tables.lua: add "focus" and "focustarget" to pfValidUnits — the
focus frames now follow the standard event-driven CreateUnitFrame path
with f.label = "focus"
- modules/focus.lua: rewrite. Slash commands use FocusUnit / ClearFocus
directly; no more manual frame.label/unitname/id manipulation. /focus
<name> still does a target-swap to resolve names → units, then
FocusUnit("target") captures the GUID before the target is restored.
PLAYER_FOCUS_CHANGED triggers immediate frame refresh on assign/clear.
- api/unitframes.lua: delete the pseudo-focus block (per-tick "scan all
units for matching name" loop) and the "focus"/"focustarget" special-
case in the visibility branch — "focus" is now a real token.
- modules/castbar.lua: bind the focus castbar to unitstr = "focus" once;
drop the OnUpdate that synced pfUI.castbar.focus from
pfUI.uf.focus.label/unitname. UnitGUID("focus") resolves at read time.
- Drop C_Minimap.SetFocusByGUID / SetFocusByName / ClearFocus calls —
C_Minimap subscribes to PLAYER_FOCUS_CHANGED on its own.
Net -183 lines. Focus stops being a pfUI-special pseudo-frame and
becomes "just another unit token" — same treatment as target/player.
* add nameplate to valid units
